EE380: Section 2: Quiz 1 (5 minutes) – Feb 02, 2011 (set 1) – solutions Student ID: Name: Signature: Given: An analog music signal extends from 0 to 12kHz. The signal needs to be Sampled and Quantized for transmission as a binary digital signal. The sampling should not lose any precision. The quantization should be done with 2048 levels. The transmission should be done using as minimum data rate as possible. Q1: What is the sampling rate you would choose? Ans: 24kHz or 24 k samples/sec (twice the maximum frequency) Q2: What is the rate at which you will transmit the signal (in bits/sec)? Ans: 24 ൈ log 2048 ൌ 264 kbits/sec Q3: What is the maximum width (in seconds) of a pulse you can choose to transmit this signal? Ans: ଶ଺ସ,଴଴଴ ൌ 0.000003788 seconds
